PAINT WHEEL SETTING ARRANGEMENT IN DUPLICATING PRINT DRUMS WITI-I PUNCH CONTROL MEANS BACKGROUND OF THE INVENTION It is known to mount in a cavity of printing drum of a rotary duplicator, an ordinal set of stamping wheels which make imprints on a copy sheet together with the imprints of the master sheet which is mounted on the printing roller. A line of alphanumerical characters, or only of digits, can thus be imprinted on a card on which other information is printed by duplicating operations.

The stamping wheels are comparatively small, and are manually set by an implement which is inserted into recesses which are provided adjacent the digital types of the stamping wheels. This setting operation is very time consuming, and the recesses are worn off by the frequently inserted implement, and do not properly hold the same so that setting errors occur.

It is also known to provide a setting device which is disposed outside of the printing drum, but which does not permit the mounting and removal of a master sheet on the printing drum. Furthermore, the stamping wheels are not reliably arrested when the setting device is lifted off, so that a correct setting is not assured. Nevertheless, the use of an implement inserted into digital recesses is still required. When the printed cards are to be punched at the same time, it is necessary to set the numbers first on the stamping wheels and then in the punching device, independently of each other, which is a cause of errors, and may result in printing of different information by the stamping wheels, than is punched by the punching device.

SUMMARY OF THE INVENTION It is one object of the invention to overcome the disadvantages of known setting devices, and to provide a setting device which is convenient for manual operation, does not interfere with printing operations of the printing drum, and assures the accurate setting of the stamping wheels.

Another object of the invention is to control the storage means of a punching device by electric sensing means which sense the positions of the setting means of the setting device, so that the punched information is identical with the stamped information.

Another object of the invention is to indicate the positions of the stamping wheels by indicia on the larger setting means so that the set information can be easily read by the operator of the machine.

Another object of the invention is to electrically display the numerical indicia to which the stamping .wheels are set.

' rorsystem for reflecting the indicia indicating the stamped information toward the eyes of the operator of the machine.

An embodiment of a stamping wheel setting arrangement according to the invention comprises a printing drum mounted on the frame of a rotary duplicating machine for rotation, and having a cavity forming an opening at the peripheral surface of the printing drum; a set of stamping wheels'rotatably mounted in the cavity of the printing drum, each stamping wheel having a plurality of angular positions, and a plurality of type portions; a support in the form of a casing having an inoperative position retracted from the printing drum,

and an operative position located adjacent the peripheral surface of the printing drum and also adjacent the cavity in one position of the printing drum; a set of manual setting means, preferably levers with handle portions, mounted on the support casing for movement with the same between the inoperative and operative positions, and also for setting movement relative to the same; and a set of transmissions for connecting the setting means with the stamping means, respectively, in the operative position.

Each transmission includes a first transmission member such as a first gear secured to the respective stamping wheel for rotation therewith, and a second transmission member, such as a gear segment connected with the respective setting lever.

The stamping wheel can be manually set by the setting levers from outside of the cavity and peripheral surface, while the support casing is in the operative position. In the inoperative position of the support casing, the gear segment portions of the setting levers are spaced from the cavity and the driving connection between the setting levers and the stamping wheels is interrupted so that the printing drum can perform a printing operation.

In the preferred embodiment of the invention, each transmission includes a gear segment means mounted in the cavity on the printing drum for angular movement, and having a gear segment meshing with the respective setting gear of a stamping wheel, and another gear segment meshing with the gear segment portion of the respective setting lever in the operative position of the supporting cases, and being separated from the same in the inoperative position of the supporting casing.

Preferably, the setting levers are double-armed and are mounted on the supporting casing for angular movement about a common axis. Each of the levers has a longer manually operated arm, and a shorter arm having a gear segment portion. Means are provided on the supporting casing for indicating the angular positions of the longer arms in the operative and inoperative positions of the supporting casing. Preferably, a number segment having numerical indicia is secured to each layer, and the row of indicia indicating the positions of the stamping wheels, can be viewed through a slot in the supporting casing in both positions of the casing.

It is advantageous to provide the setting levers with handle portions, and to arrange the handle portions of alternate levers so that they are spaced at least 45 whereby more space for the operator's finger is available, and no implement has to be used for the setting operation.

The supporting casing is preferably mounted on a stationary shaft for angular movement, and the inoperative and operative positions are preferably spaced an angle greater than 30".

It is advantageous to provide arresting means for the gear segment portions of the setting levers which become immediately effective when the supporting casing is turned out of its operative position, and the meshing gears of the transmissions separate.

In the preferred embodiment, the supporting casing with the setting levers is automatically locked in the retracted inoperative position, and is unlocked by an electromagnetic means only if the printing drum is in an angular position in which its cavity with the stamping wheels therein, is properly located to cooperate with the setting means in the supporting casing when the same is moved to the operative position. A switch connected in series with the electromagnetic means, and operated by a cam on the printing drum obtains this result.

Another safety measure is to prevent operation of the starting lever of the printing machine, as long as the supporting casing with the setting means is in the operative position, and the transmission gears mesh. A switch connected in series with a blocking magnet for the starting lever, and being operated by the supporting casing, obtains this result.

It is advantageous to provide additional arresting means for manually arresting the supporting casing in the operative, as well as in the inoperative position.

In the preferred embodiment a mirror system is used for reflecting numerical indicia representing the selected types of the stamping wheels, toward the eyes of the operator.

In the preferred embodiment a set of contact plates is fixedly mounted on the supporting casing adjacent the setting levers, respectively, and each setting lever supports a brush sliding over the contacts of the correlated contact plate during setting movement. An electric circuit connects the brushes and contacts with a storage device so that information regarding the set types is stored, and can be used for controlling a conventional punch.

The novel features which are considered characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 4 illustrate a preferred embodiment of the invention in which lateral frame walls 12 and 13 support the shaft 2 of the printing drum 1 of a rotary duplicator. Printing drum 1 has a cavity la in which a shaft means 3, extending parallel to the shaft 2 of the printing drum 1, supports a set of stamping wheels 4 to which gears 5 are secured, respectively. Each stamping wheel 3 has a peripheral set of type portions 4a, one of which is flush with the peripheral surface of printing drum 1, on which a master sheet 1b is mounted. Consequently, during a printing operation, the respective type portions 4a of all stamping wheels 4 are effective to print a line on the copy sheet or card receiving imprints from the master sheet lb.

A set of gear segment means 6 is mounted on shaft 7 in the cavity In, and each gear segment means 6 has a gear segment portion 8 meshing with the respective gear 5, and a staggered gear portion 9 meshing with a gear segment portion 16 of a double-armed setting lever 16a. Alternate setting levers 16a have projecting finger engaging portions 18 and 19 which are angularly staggered so that more room is available for the finger of an operator pressing either against a finger engaging portion 19 or against a finger engaging portion 18, as best seen in FIG. 4. All setting levers 16, 16a are mounted for independent turning movement on a shaft 17 supported by the lateral wall of a support casing 15 which has a curved top plate 15a.

A support shaft 14 is mounted in the stationary frame walls 12 and 13, of which only support wall 12 is shown in FIG. 4. Support casing 15 is mounted at one end for angular movement about stationary support shaft 14, and as shown in broken lines in FIG. 1, support casing 15, with shaft 17 and the setting levers 16, 16a, can be turned between the operative position shown in solid lines in FIG. 1, and the inoperative position shown in broken lines, an angular distance of at least 30. The finger engaging portions 18 and 19 of adjacent setting levers 16, 16a are spaced an angle of at least 45.

When support casing with setting levers 16, 16a is turned to the inoperative position away from the printing drum 1 and the cavity la, the gear segment portion 16 of each setting lever 16a separates from the gear segment portion 9. Gear segment means 6 has an arm 6a with arresting recesses 6b engaged by a spring loaded arresting member 11 which is mounted on the printing drum 1. Consequently, the stamping wheels 4 cannot be accidentally displaced during the separation of the gear segment portion 16 from the gear segment portion 9 or during engagement of the same. A pair of arresting members 21, 22 is mounted for scissor-like movement on a shaft 20 supported by the side walls of support casing 15, and one pair of end portions of arresting members 21 and 22 is urged apart by a spring 23, so that the arresting portions 21a and 22a at the other ends of arresting members 21 and 22 fall into corresponding recesses 24 provided in the fixed support shaft-14, so'that it is not possible to turn support casing a with the setting levers 16a to the inoperative position, unless arresting members 21 and 22 are manually operated. In the turned inoperative position of support casing 15 with setting levers 160, the arresting portions 21a and 22a engage another pair of arresting recesses 26 due to the action of spring 23, so that support casing 15 is also arrested in the inoperative position shown in broken lines in FIG. 1.

In the operative position of support casing 15, any setting lever 16a can be angularly displaced by the operator engaging either finger engaging portion 18 or finger engaging portion 19 for placing a selected printing portion 4a in the operative position flush with the surface of the printing drum 1. Each setting lever 16a has a segment shaped portion 28 provided with numerical indicia corresponding to the numbers represented by the type portions 4a of each stamping wheel 4. Assuming that the set of stamping wheels 4 has been set by the corresponding setting levers 16a, a row of numerical indications, corresponding to the numerals which will be stamped by the set of stamping wheels 4, is located under a slot 27 of support casing 15 so that the operator can directly read out the position of the stamping wheels 4 by viewing the indicia of the setting portions 28 through slot 27. Since the lever arms with the indicia carrying segments 28 are much longer than the lever arms of the gear segment portions 16, the indicia can be larger and better readable than in constructions in which the indicating number wheels are located in the cavity of the printing drum.

When the setting of the stamping wheels 4 has been completed, the ends of arresting members 21, 22 are pressed together so that the arresting portions 21a and 22a release the recesses 24 in support shaft 14, and support casing 15 can be turned to the position shown in broken lines. When arresting members 21, 22 are manually released, spring 23 causes arresting portions 21a, 22a to enter the recesses 26, so that the support casing is locked in the inoperative position shown in broken lines, permitting the attachment of a master sheet lb, and also rotation of the printing drum during a printing operation in which the selected type portions 40 and also the master sheet lb make imprints on a copy sheet.

The above described manual arresting of support casing 15 with setting levers 16a, permits an erroneous operation in which the support casing is lowered to the operative position while the printing drum 1 rotates, and would also permit starting of the printing drum while the support casing 15 with setting levers 16a is in the operative position. In order to prevent such errors, a locking device is provided for locking support casing 15 in the inoperative position, and this locking device 30 to 35, best seen in FIG. 2, includes an electromagnet 32 mounted on a side wall of support casing 15, a locking member 30 pivotally connected with the armature of electromagnet 32 and being biased by the spring of the same to engage a locking arm 33 which is adjustably mounted on a link connecting fixed shaft 14 with another fixed shaft 34, also mounted on frame wall 13.

In the position of support casing 15 shown in broken lines, locking member 30 engages locking arm 35 due to the action of spring 31, and prevents turning of support casing 15 to the operative position shown in solid lines. However, when electromagnet 32 is energized, locking member 30 releases locking arm 33, and support casing 15 can be turned to the operative position.

FIG. 2 further shows a switch 54 operated by a cam Zn on shaft 2 of the printing drum. The respective circuit is shown in the left portion of FIG. 5 in which the electromagnet 32 is shown to be connected in series with the cam operated switch 54, and a switch 52, see also FIG. 4, which is closed when the starting lever 37 of the duplicating machine is in the position shown in solid lines in FIG. 2. Electromagnet 32 is energized in the position in which the closed cam operated switch 54 indicates that the cavity 1a is correctly positioned and when the closed switch 52 indicates that the printing machine has not been started.

On the right side of FIG. 5, and also in FIG. 2, a blocking electromagnet 36 is shown which blocks movement of starting lever 37 in the position shown in solid lines when energized upon closing of a switch 55, see FIG. 2, which cooperates with the support housing 15 in the broken line position, and is held open by the same so that blocking electromagnet 36 is deenergized, and permits movement of starting lever 37 out of the solid line position in clockwise direction as viewed in no.2.

After electromagnet 32 has unlocked support casing 15 in the broken line position, and the same is moved towards the solid line position, switch 55 closes automatically, so that blocking electromagnet 36 is energized and its armature moves to a position preventing operation of starting lever 37 so that rotation of the drum cannot be accidentally started while the support casing 15 and the setting levers 16a have been moved to the operative position.

While starting lever 37 is blocked by the magnet 36, and printing drum 1 is in the position shown in FIG. 2, support casing 15 with setting levers 16a can be moved to the operative setting position shown in FIGS. 1 and 2 in solid lines, so that the stamping wheels 4 can be set.

When the setting operation has been completed, support casing 15 is turned upward to the inoperative position shown in broken lines, so that casing switch 55 opens, and blocking magnet 36 is deenergized, permitting operation of the starting lever 37.

When starting lever 37 is moved in clockwise direction beyond the position shown in solid lines, switch 52 is opened so that the electromagnet 32 is de-energized, and locking member 30 is moved by spring 31 to a position engaging locking arm 33 so that support casing 15 is locked in the upper inoperative position. When printing drum 1 starts to rotate, cam 2a releases switch 54, also disconnecting electromagnet 32 from the source of voltage schematically indicated by plus and minus signs in FIG. 5.

FIGS. 3 and 4 illustrate another arresting means for arresting the setting levers 16a, so that the indication under slot 27 cannot be disturbed during movement of support casing 15 between the operative and the inoperative positions. An arresting member 44 is mounted on a shaft 43, which is supported in the support casing 15, for angular movement. Arresting member 44 is urged by springs 45, 46 to a position engaging aligned recesses of the gear segment portion 16, so that all setting levers are arrested when arresting member 44 engages the gear segment portion 16.

Actuating arms 50, 51 are secured to support shaft 14, and engage projections 44a in the operative position of support casing 15, so that springs 45, 46 cannot turn arresting member 44 to the arresting position. Fixed stops 47, 48 are engaged by projecting portions 50a and 51a of arms 50 and 51, so that arms 50, 51 cannot turn in clockwise direction in the position of FIG. 3.

As shown in broken lines in FIG. 3, arresting means 44 is released by the arms 50, 51 when support casing 15 is turned a very small angle toward the position shown in broken lines so that gear segment portions 16 are immediately arrested when support casing 15 is moved out of the operative position shown in FIG. 3, in which gear segment portions 16 cooperate with gear segment means 6, and gears as shown in FIG. 1.

As shown particularly in FIG. 2, the indicia on the segment portions 28 can be read out by an operator on theright side of the duplicating machine, as viewed in FIG. 2, through the slot 27, which is particularly used during a setting operation when the support casing is in the lower operative position shown in solid lines in FIG. 2. However, when the support casing 15 is turned to the inoperative position shown in broken lines in FIG. 2, slot 27 is located rearward of the printing drum, and cannot be viewed properly by the operator. As particularly shown in FIG. 9, a support 38 on the frame means of the printing machine, supports an angular housing 38a in which a lamp 100 is mounted behind a lower mirror 42 which forms an acute angle with a downward facing horizontal mirror 41, which is located along a radius passing through the support housing 15 at 27. The indicia on segments 28, which form a row under slot 27, are reflected by mirror 41 toward mirror 42 and by the same toward the eyes 102 of an operator which stands on the right of the machine, as viewed in FIG. 2. The lamp 100 is positioned to illuminate the indicia through slot 27, but is shielded by mirror 42 so that the lamp 100 is not visible to the operator. The angles of mirrors 41 and 42 may be adjusted in a suitable manner. The mirror image formed by mirror 41 is transformed into a real image by the second mirror 42.

In order to permit the storing and indicating of the information set by setting levers 16a and stamped by stamping wheels 4 at a remote station, a set of contact plates 59 is provided, as shown in FIG. 6, each contact plate 95 being located adjacent a setting lever 16a, and being correlated with the same. Each contact plate 95 carries a printed circuit 95a having contact means 96 respectively associated with a 10 digits, and cooperating with a pair of brushes 97a of a brush holder 97 secured to the respective correlated and adjacent setting lever 16a. The contacts of the printed circuit 95a are arranged in circles having the center in the axis of shaft 17 about which the setting levers 16a turn, so that brushes 97a seccessively slide over the contacts during the setting movement of the respective setting lever 16a, and rest on a contact representing the same digit as the respective setting lever 16a and correlated stamping wheel 4. Connector pieces 98 are connected with each contact of printing circuit 95a, and are connected by wires, to electric display lamps 100, as best seen in FIG. 8 which also shows the connections between contacts 38 and punch controlling magnets 77 of the storing device of a punching apparatus shown in FIGS. 7 and 7a.

The punching device shown in FIGS. 7 and 7a, and the electrical connections with the same are known, and disclosed in my US. Pat. Nos. 3,502,262, and 3,508,487.

A series of actuator bars 58 is provided, of which only one is visibiel in FIG. 7. A shaft 59 carries a cam 60 and is driven from a drive shaft 61 by a worm gear transmission 62. A cam follower member 63 has a roller 64 cooperating with cam 60, so that cam follower lever 63 is angularly reciprocated about a supporting shaft 66 while springs 72 and 65 are alternately tensioned. When cam follower lever 63 tensions the spring 65 which is secured to a pin 92 on frame of the machine, a transporting link means 68, which is connected with spring 72, and pivotally connected by a pin 67 with cam follower lever 63, is moved in the direction of the arrow C. Pivot means 69 connect transporting link 68 with a guide block 70 which has a slot receiving actuating bar 58, and a coupling pawl 65 mounted on block 70 by means of a pivot, and being biased by spring 76 so that coupling pawl is biased to engage a recess in actuating bar 58. Consequently, actuating bar 58 moves with the respective transporting link 68 in the direction of the arrow C.

A punch control magnet 77 for each actuating bar 58, has an armature 82 for operating a pawl 81 mounted on a stationary pivot and having pointed portion engaging one of ten recesses 83 in the respective actuating bar 58, only one recess 83 being shown for the sake of simplicity.

As shown in FIG. 8, each punch controlling magnet 77 is electrically connected with a brush means 57 operated by a selector lever 16a as described with reference to FIG. 6.

A set of ten switches 79 is provided which are successively actuated by angularly staggered cam lugs 78 secured to shaft 59, as shown in FIG. 7a. Shaft 59 also carries cams 8, as shown in FIG. 7. When switches 79 are successively operated, the punch control magnets 77 are successively energized so that the respective pawl 81 engages one of the 10 recesses 83 in the respective actuating bar 58, as determined by the set position of the respective setting lever 16a and the brushes 97 of the same.

When an actuating bar 58 is blocked by an actuated pawl 81, a portion 85 thereof is also blocked so that a single punch hammer 84, biased by a spring 89 to an upper position, is located directly above one punch 86 of a series of IO punches. In a manner which is not an object of the present invention, the punch actuator 88 is moved downward so that hammer 84 pushes punch 86 with which it is aligned, against the action of the spring 91 to a punching position penetrating the card 57 which rests on a base provided with bores into which the end portion of a selected punch enters after penetrating the card 57.

Since actuating bar 58 is blocked by blocking pawl 81, coupling pawl 75 is pressed out of the recess of actuating bar 58 due to the movement of the block 70. After the punching operation, roller 64 engages a lower portion of the cam track of cam 60, and lever 63, transporting link 68 and block 70 are returned by spring 65 to the initial position. During return movement of block 70, the coupling pawls 75 again engage the respective recesses and transport the actuator bars 58 to the initial positions. The punching operation takes place after turning of shaft 59 through an angle of about 180.

The actuatorbars 58, 85 together with electromagnet 77 and pawls 81, constitute means for storing the information received from the printed circuit 95, 95a, 98 due to brushes 97a.

Referring again to FIG. 8 it will be seen that successive closing of the switches 79 by the cam lugs 78 causes successive energization of the punched control magnets 77 so that the respective punch hammer 84 is accordingly set. Diodes 101 between punch control magnets 77, and ground, prevent energization of all punch control magnets 77 simultaneously when one switch 79 is closed and connected to the positive terminal of the voltage.

A display lamp 100 is provided for each setting lever 16a and printed circuit 95a. The cam operated switches 79 successively interrogate the printed circuits 95a of the setting levers 160 so that the respective selected and set digit is illuminated and displayed by each lamp 100. The display lamps 100 are preferably mounted on the support 39 shown in FIG. 2, and can be easily observed by the operator.

From the above description of a preferred embodiment it becomes apparent that digital or other information set in a stamping device in a cavity of a duplicating drum, can be read-out in any position of the printing drum, while the set values are simultaneously transferred to a punching device for punching holes representing the selected and set value into punch cards.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of stamping arrangements for printing machines differing from the types described above.

While the invention has been illustrated and described as embodied in an arrangement for setting a set of stamping wheels located in a cavity of a printing drum, by a setting device located outside of the printing drum and having means for indicating the set positions of the stamping wheel, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
